龙厦铁路石桥头隧道地表建筑物变形监测方法及计算分析

The Deformation Monitoring Method and the Computing Analysis of Building on ground surface at Long Xia Railway Shiqiao Tunnel

石桥头隧道横跨龙岩市区,隧道长、埋深浅、岩质差、地表建筑物密集。在隧道开挖初期,建筑物出现较大沉降、倾斜、拉裂和错裂,严重影响建筑物正常使用,危及居民安全。为此对建筑物进行了沉降监测、水平变形监测和倾斜监测,并计算建筑物的曲率,取得很好的效果,且对隧道施工起到很好的指导作用,本文简要的研究了其监测方法及计算分析。

Shiqiao tunnel across Longyan,the tunnel long,buried deep,rock poor,the building on ground surface of the tunnel was dense.In the early stage of tunnel excavation,the buildings appeared large sedimentation ,inclination,pull-and-error ,which had seriously affected the normal use of the buildings, endangered the safety of resident^therefor,we did settlement monitoring, level deformation monitoring and tilt monitoring for the buildings, and calculate the curvature of them,which obtained good results,and played a guide important for the tunnel excavatiothis article compendiously researchs its monitoring methods and computational analysis.
